DOUBLE-ACTING COMPACT POWER-PUMP.

Specification of Letters Patent.

Patented Oct 1,191 2.

Application filed April 6,1910. Serial No. 553,748.

To all whom it may concern:

Be it known that I, SIDNEY S. SMITH, a citizen of the United States, residing at Seneca Falls, in the county of Seneca and State of New York, have invented certain; new and useful Improvements in Double- Acting Compact Power-Pumps, of which provements in power pumps, but inasmuch as certain advantages characteristic of thesame prominently appear in its more intense aspect as a double acting horizontal force-pump having a substantially unitary body casting, it will be conducive to clearness to fully disclose this invention through a detailed description of such embodiment.

One object within the contemplation of' this invention is to render available a pump which is composed of very few separateparts and in which a single main casting; embodies many elements which have heretofore constituted separate elements of machines of this class.

Another object of this inventlon 1s to ren- 'der available a pump characterized by great simplicity, durability and general efiiciency.

and in which the general construction shall be such that all parts are easy of access and readily adjusted for wear or otherwise.

A further object is to provide a pump of the most compact design consistent with its capacity, and which will provide large and easy waterways, and a superior structural strength throughout.

A more specific object is to so design the pump that, while the same will be notably high-grade, the manufacture of the same will entail but few machine operations and thus enable the device to be produced at a minimum of factory cost. I

Another and more specific object is to so locate and arrange the various shaft bear ings that the same may be rigidly supported, conveniently and well disposed, from a mechanical standpoint, and. provided with ample means for lubricating the various journals of the device.

Other objects realized by the preferred more specific embodimentof the invention are: to employ cylindrical waterways of great capacity thus utilizing the shape affordlng a maximum strength for the metal used and at the same time facilitating corework and molding; to give the valves and seats therefor a circular shape and thus promote ease and accuracy in the construction thereof; to provide conveniently located hand-holes for gaining access to such valves without disturbing any of the working parts; to simplify and render more positive the means for keeping tightly closed the covers for such hand-holes; to provide an arrangement whereby a single removable piston-head suflices for the pumping cylinder and to support the main crank shaft directly on an integral part of the main casting on the side opposite that from which the piston-rod protrudes.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In order that the more salient features of this invention may be more fully understo-od, drawings exemplifying one of the many possible embodiments thereof are annexed as a part of this disclosure and in such drawings, like characters of reference denote corresponding parts through several views, of which- Figure 1 is a side elevation showing the general external appearance of the pump and displaying certain of the broad features of construction thereof. Fig. 2 is a view somewhat similar to Fig. 1, but showing certain parts broken away to more clearly exhibit certain details of construction and arrangements of parts of this device. Fig. 3is, an end elevation looking toward the right as shown by Fig. 2, 2'. 6., toward the crankshaft end of the pump, and showing the general assembly of the pump from another viewpoint. Fig. 4 is atop or plan view showing certain parts and relation ships therebetween not so clearly apparent from the foregoingfigures. Fig. 5 is a vertical irregular section taken along the broken line 5.5 of Fig. 2 showing the crosssectional contour of the upper and lower crossways. Fig. 6 is a horizontal section through the body portion taken along line 6-6 of Fig. 2. Fig. 7 is a horizontal section taken along line 77 of Fig. 2. Fig. 8 is a plan view of the cap for securing the emplification, turning occasionally to they drawings as indicated by the reference characters, it may be prelimlnarily stated that this 1nvent1on proposes a construction in which separate parts are dispensed with, so. far as may be practical within the limits of commercial considerations and to that end, the body casting A 1s arranged to form not only the pumping cylinder itself, butalso the inlet and outlet waterways and at the same time provide bearing-supports for the actuating-shaft, the main-crank shaft,

and the guide-rods for the piston crosshead. The pumping cylinder occupies a central position in this embodiment of the invention and is formed by a cylindrical shell 1 which is integrally connected adjacent its end with the two opposite, parallel, cylindrical upright waterways 2 and 3 respectively. If desired, the cylindrical shell 1 forming the pumping cylinder may have its ends projecting slightly into the waterways as indicated by 4 and 5 thereby slightly increasing the capacity of the cylinder and lengthening the stroke of the piston without materially restricting the capacity of the waterways. In order that the interior of the pumping cylinder may be readily bored out in the process of manufacture, and to provide for the admission of the piston, this invention contemplates an opening 6, shown more clearly by Fig 5, extending through the outer wall of the.

upright waterway 2, and in register with the interior of the pumping cyllnder.

diameter with the pumping cylinder and thus enables the piston to be readily introduced into the cylinder. This opening is preferably on the piston-rod side of thepiston, so that the cover closingthe same,

may also carry the stuffing-box for the piston-rod. bolted in place by means of the bolts 8 and it is furnished with a gland sleeve 9 which cooperates in the usual way with suitable; packing and can be drawn tight by means;

of the gland bolts 10. The piston may be of any desired shape but preferably consists of three disk like members 11, 12 and 13,

(shown more clearly by Fig. 2) which areheld in place on the piston-rod 14 by means rod 32. crank-shaft 42 is a crank-plate 90 which is As. shown, this opening is fully coextensive in Thus, as shown, the cover 7 is;

of the lock-nuts 15 and 16. The guiding and actuating means for the piston-rod 14 comprises a cross-head 17 which is bolted to the piston-rod 14 by means of the lock-nuts 1S and 19 and this cross-head 17 preferably has a sliding bearing on two oppositely positioned guides. Such guides are preferably .formed by two sections of turned shafting 20 and 21 which are slightly reduced as shown by the dotted lines 22 and 23 at their secured ends, these reduced portions passing through corresponding apertures in the lugs 24 and 25 which are preferably cast integral with the corresponding upright waterway shell. These guide-rods 20 and 21 are then retained against withdrawal by means of the nuts 26 and 27 as will be perceived. This forms a very simple, inexpensive, and at the same time effective and durable method of providing guide-rods for the cross-head 17. In order to reciprocate the piston-rod 14 through the instrumentality of the cross-head 17, the latter preferably terminates' at its extremities in two gudgeons 28 and 29 on which are journalcd the ends 30 and 31 of the connecting rods 32 and 33 respectively, and to prevent lateral displacement cotter or taper pins 34 and 35 may be passed through the protruding ends of the gudgeons 28 and 29. On the opposite side of the body-casting, and preferably formed integral with the upright waterway shell 3, is a bearing boss 36 which is completed in structure by a bearing cap 37 held in place by bolts 38 and 39. This bearing cap 37 preferably also provides a suitable oil-well 40 cast integral with the same, which oil-well may be closed by a hinged flap 41, as will be readily understood. The above described parts form the bearing for the crank-shaft 42, which passes from one side of the machine to the other, and on the one side carries a large gear 43 to which is afi'ixed the crank-pin 44 on which is journaled the enlarged end 45 of the connecting Mounted on the other end of this keyed or otherwise locked to the shaft 42 and which also carries a crank-pin 91 on whichis journaled the large end 92 of the connecting-rod 33. Through this construction, it will be evident that great compactness in the arrangement of the pump-body,

the crank-shaft, the gear 'for actuating the crank-shaft, the connecting-rods and the vcross-head for the piston is attained, and

the partition 53.

addition to the two vertical upright water ways 2 and 3 and the intermediate horizontal pumping cylinder 1, a lower fluid cross-way 46, an upper fluid cross-way 47 and a riser 48 leading to the dome 93.

The lower cross-way 46 combines the dual functions of a means for enabling the water to enter the pump and a suitable support for the entire structure.

To that end, integral extensions 49 in the form of feet (see Figs. 2 and 3) serve as a base for supporting the entire pump, and these extensions may be provided with bolt recesses 50 y of operation of the piston in the pumping cylinder. Thus, assuming that the piston shown in Fig. 2 is about to begin its travel toward the left, the water will enter the ports 51, and thence travel through the ample space indicatedby 52 on Fig. 2 into underlying proximity with the horizontal partition 53 formed in the lower part of the upright waterway 2. At this point is lo cated a suitable check-valve which enables the water to rise and checks its fall. A very satisfactory construction in this respect consists in first manufacturing the checkvalve complete in the form of the unit shown by Fig. 10 and then inserting the samein place in the pump through suitable openings. To that end, the base portion 54 of the check-valve has a tapered periphery 55 which is adapted to be driven home in a correspondingly formed circular aperture in A check-valve stem 56 rises centrally from the base portion 54, is provided with a head 57 at its upper end, and slidably centers the valve-flap or plate 58. The expansile spring 59 circumscribes the shank of the stud 56 and intervenes be tween the head 57 and the flap 58 and normally serves to retain the latter in place. A brass disk may be interposed between the lower end of the spring 59 and the flap 58 if desired, as shown by Fig. 10, and the headed end of the stud 56 may be socketed to facilitate its removal with a wrench if desired.

It should here be observed that various forms of check-valve are available in this connection, but that illustrated is simple, durable and otherwise satisfactory in service, i

ably cored casting as will be readily underand is therefore preferred.

In order to gain access to the above mentioned parts for the purpose of inserting the valve in place or for the purpose of machining and screw-threading the openmg inthe partition 53 during the process of manufacture, the side of the vertical waterway 2 is provided with an amply large opening or manhole 95 similar to that indicated by 60 on the opposite vertical waterway in; Fig. 2. This opening is closed by means of a suitable cover plate 62 shown by Fig. 7, and the opposite waterway is identically constructed in this respect and provides a similar cover plate 63. Attention is particularly directed to the fact that these openings are arranged on the same side of the two upright waterways and this arrangement is utilized in retaining the cover-plate in place in a very positive yet essentially simple manner. This consists in providing the lower cross-way 46 between the two upright waterways 2 and 3 with a cross-flange 64 which is provided with a central recess 65 adapted to receive the shank 66 and retain the head 67 of the tension-bolt against the edges of such recess. This tension-bolt at its other end loosely passes through an aperture passing centrally through a yoke 68 which terminates at its opposite ends in abutment-balls 69 and 70 which in turn bear against counterpart central recesses in the plates 62 and 63. By screwing up the nut 71 on the end of the shank 66 of the bolt, the yoke 68 ,is caused to press the covers 62 and 63 in place tightly, yet with perfect equality, thereby absolutely preventing leakage or the like. The upper valve construction of the upright waterways 2 may now be described. This is shown more clearly by Fig. 2 and in this case, it suiiices that the upper ends of the upright waterways 2 and 3 are provided with centrally apertured horizontal partitions 72 and 7 3' and are provided with suitable check-valves 74, analogous to the con.-

struction above described with reference to the lower part of the upright waterway 2. A difference, however, exists in thisrespect: The opening for gaining access to the valves, instead of being arranged at the sides of the upright waterways, is preferably disposed at the top ends thereof. Thus, as shown by Fig. 2, the upright waterway 2 has in its upper extremity the large opening 7 5 which i is closed by a circular cap 76. A corresponding construction and similar cap 77 is resorted to in connection with the other waterway 3. Between the cap 76 and the valve 74is provided an ample passage 7 8 for the flow of the fluid, which passage forms the interior of the upper horizontal cross-way 47which leads to a central and vertical conduit or passage 79 formed by the upright tube 48. All this is formed by a single suitstood from the annexed drawings. The upthe dome 93 havingthe discharge outlet 96,

the bolts 100.

and which is also utilized as an abutment for the engaging end 81 of the yoke 82 which provides a ball-abutment 83 co-acting with a corresponding depression in the cap 76. A bolt 8 passes through a suitable aperture in the lug 85 cast on the upright waterway 2 and is retained against withdrawal by means of its head 86 and has a nut 87 which is screw-threaded to its other end and is adapted to be turned to regulate the tension of the yoke 82 and thereby close the cap 76 with all desired tightness. The cross-way 4L7 is also very conveniently utilized'as a support for the bearing of the driving or pinion shaft. That is to say, the under portion of this cross-way 417 is cast in the form of a half-section 98 of a j ournal-box, which half-section provides integral'corner parts 99 apertured to receive The counterpart or lower half-section 101 of the journal-box is elongated and consists of a supported part 102 which, by means of the above-mentioned bolts 100, is secured to the upper half-section 98, thereby completing the journal-box; and it also consists of the extension bearing 103 which provides a well 104 for receiving and retaining the lubricant. This lower half-section also has a well 105 located directly under the part 98, as indicated by Fig.

8. A cap 106 is, by means of the bolts 107,

secured to the part 103, thereby completing an auxiliary journal-box adapted to embrace the driving-shaft 108 adjacent the fast and loose belt-pulleys 109 and 110. This driving-shaft 108, or pinion-shaft, as it may be termed, has keyed to the end which protrudes from the other side of the pump, a pinion 111 which is in mesh with the large gear 43 and serves to drive the latter.

From the foregoing it will be quite evident that the above-mentioned objects and advantages have been very fully attained by the herein disclosed embodiment, and that the several parts are exceedingly simple, compact and capable of operating under a high duty.

As a matter of convenience, and for the sake of brevity, the terms vertical, horlzontal and the like, have been freely resorted to in.

the specification and claims, but it is to be understood that such terms have been merely adopted as expressing a relationship.- between parts, and are not to be regarded as limiting the posit-ion which the'device may assume in space, since it will be obvious that for various purposes one or more of the elements of the device may be so arranged as to occupy various absolute positions in space without, however, materially altering the relationship between the various essential elements of the invention.

Without further elaboration and in the light of current knowledge, the foregoingdisclosure will sufficiently suggest and otherwise render obvious to those skilled in this art certain interchangeably available structures which, although perhaps calculated to appear widely different, under a superficial examination, from that herein illustrated, would nevertheless embody certain of the herein-disclosed features which, from the aspect of the prior art, constitute essential characteristics of this invention, and it is therefore to be understood that such structures should and are intended to be co1nprehended within the scope of the annexed claims.
